Abstract

The present invention relates to a process for the preparation of polyaluminium hydroxychloride complexes having the general formula Al(OH)xCly in solution or in solid form and intended to be used as flocculants and coagulants at water purification, sludge dewatering, plant dewatering and paper production, whereby one reacts aluminium chloride in solution with aluminium hydroxide, or aluminiumoxide hydrates at a temperature of 120-170 DEG C at an elevated pressure for 1.5-5 hrs, whereby the relationship AlCl3:Al(OH)3 is thus adjusted that the relationship OH:Al in the resulting compound Al(OH)xCly becomes 0.5 to 1.5, preferably 0.8 to 1.2.
